Be it known that I, JOHN W. KUHRT,

a citizen of the United States, and 'a'resident of Toledo, in the county of Lucas and State of Ohio, have made an lnventlon Appertaining to a Doorstop, which invention is fully set forth in the following specification. I

This invention relates to door stops and catches, and has for its object the provision of a simple, efiicient and durable device of this character, which may be used 'elther as a stop or buffer to limit: the opening movements of a door, or as a catchto hold. a door in'releasable open position, the catch; means being moved to operable door engaging position bya movement imparted to they stop or buffer means by a door when strik- The invention is in numerous forms, two embodi'mentsonly thereof are illustrated in the accompanying drawings, in which i Figure'l is a vertical central longitudithrown to door engaging position. Fig. 3 is a fragmentary view similar to Fig; 1

and partly in full, with the door stop'locked against catch op'erating movements'.= Fig. '4: is a side'elevation'of a different :formOf the device adapted particularly -for-o1it-r side workwith a'door' inx'the' act ofstrik-- ing the stop member and moving the catch member to operative position,"thefpartsin which the device is mounted 'being frag- *mentarilvshown and"insection. Fig. "5 is g M H When "the" bufi'er 1 1' is in its forwardly a rear 'elevationbfthe "device: Y Fig. 6' is" a sectional view thereof on" the line *6-6 in Fig.5, withlpartsin full and with the 'atch means in door engaging position; and FigL 7 is a fragmentary"viewsimilar to FigL-6 3 ofthe drawings; 1 designatesa'basexplate. which is adaptedto'b'e set-into a-recess"2 provided m afloor or other "supporting? with K the" stop means locked aga-inst catch operating movements.

Referring particularlyto "Figs. "1, '2 and means 3 in position for the lower edge of I fully described in the? following specification, and while in itsv broader aspect, it is capable of embod ment;

a door 4 to swing over'the same when-moved t0 open posltion. A post or'upright member 5 rises from the base plate 1 near the, limit ofzdesired 'openingmovements of the a se t v OHIO:

doori t and is provided in its top vportion with-across opening 6 "and in its'lower'portion wlth a vertically disposed opening 7' which-text endsfrom,the opening '6 down through theplate {1,-andf into the recess 2.

-A bell crank 'lev'er member 8 is fulcrumed I at-its elbow within the lower end portion of the post opening 7, asat 9, and has one arm extending up through said opening and into the icross 'opening 6 and its othervarm 'extending-lengthwise of the plate -1 beneath the same-and in operating engagement with a catch plunger 01' stud 10, which is mounted for vertical reciprocato'ry movements in the plate '1: in spacedrelation to the post 5.

#Abuffer or stop member 11, preferably of rubber or otherwyielding"material, is car-- 'ried by the upper end of'the upright arm of the lever-8- for movements into and out of the-cross opening 6 whent'he lever is rocked,

the buffer a memberkbeing disposed" at the 'S'idefOf the lever adjacent to the catch plunger-10-.- 'When the upwardly project ingarm of the lever 8 is ini its forwardly r0cked"*position, shown in Fig; 1', the buffer 11- pro ectsa distancewithout the forward end of'the openingG-iri position to be engaged and moved distance into the ppening oby the associated door 4E striking thereagainst, thereby effecting a rocking ofTth'e 'lever'8. The-bufi'er'p11, in the presentinstance, ismountedr on the forwardly projecting end i of the upright arm 'of the lever 8 and preferably has a spherical body portion which fits into the opening 6 and has a flanged :outer end portion'b, which, when the bufier is" forceddnto the opening 6, 'coacts'with the outer' marginal t *edge-wallof'such opening to stop the further movement'ofthebuffer therein.

projecting'position, as shown'in Fig. 1, the

catch plunger 10 with which the opposite end of the'lever 8 is connected, is in lowered inoperative position to permit the door 4 to freelyi-swlng across the same. -Theinward movement" of' the buffer occasioned by the door" striking "the same causes an upward movement ofthecatch plunger g12-;in advance 'of' the lower edge of the door 4' to zholdw'theqdoor" inopen position until the plunger has been depressed to its inoperative position.
